McGoo, Tlowe also has roller rockers made for him exclusively that eliminates the need to clearance the corners of them for valve cover clearance. No valve cover spacer is required either. Also, I have found a solution for the distributor gear hobbing on my roller cam blanks and am moving forward right now. I bought a 12 ft stick of material to get 5 of them roughed out and machined to get ready to send and be hobbed and copper plated. These can be finished as either a hydraulic or solid roller version. So before long the hydraulic roller setup can be available to those who are interested in it. The Slant 6 Chrysler and Ford 300 guys are anxious to get some also. If you can't get a Cometic head gasket, you might have to consider a copper gasket as an alternative, which with an o-ringed block you will have no issues or concerns.
